NGSS.MS-LS4-2

A natural system of classification for grouping taxa based on the characteristics that have evolved most recently.

Also characteristics that have similar structure and function but have evolved more recently in the form of modification of previous traits.

NGSS.MS-LS4-2

The process of joining two single strands of DNA to form double-stranded DNA connected with hydrogen bonds between nucleotide bases

A technique that can estimate the time of the speciation events using the mutation rate of biomolecules.
